- To all whom it may concern:

further object is to provide a construction that can be oiled readily and efficiently. I

The characteristic features of the improvements are fully disclosed in the following descript on and the accompanying draws ings in illustration thereof.

In the drawings, Figure 1 is a side eleva tion of a construction embodying the invention, Fig. 2 is a sectional view taken on the line 22 of Fig. 1, Fig. 3 is a longitudinal sectional view illustrating a modified construction, Fig. 4 is a sectional view taken on the line/1 4; ofFig. 1, Fig. 5 is a perspective view of a detached bearing stud or journal, and Fig. 6 is a detached bearing of modified construction.

The mechanism, inthe form thereof illustrated in the drawings, comprises'the similar coupling knuckles 1, .having'theyoke members or bifurcations 2 disposed. transversely to each other and yoked on a sub-' stantially cubical block 3 or 3,.pintles for.

small journals 4 or 4 pas'singthroughthe respective legs of the bifurcations into the block so that each knuckle or couplingmem? her is adapted to move in a'plane at'yright angles to the plane of movement of the other.

As illustrated in Figs. 2, 4 and 5', the tles 4 have their inner ends turned to; rm channels 4* having curved surfaces concen trio with the, pintles axes, and 'similarly' b ev eled faces 4 adapted to engage so" as to -leave an open space or way 5 between'their truncated ends, each pintle containing an axial passage 4 with an angular outlet 4:? to the corresponding bearings 2 As illustrated in Fig. 2, studs 6, having the circular knife edges 6*, are screwed into the block 3 so as to engage the knife edges in the channels 4* to hold the pintles4 in place. These studs 6 are also provided with the passages 6 in alinement with the passage 5 for the introduction of Oilj-tO lubri- -cate the wearing parts, the oil flowing through the ings 2 7 As illustrated in Fig. 3, a,

single 6 vided with the channels 4, having substantially conlcal sides in place of the channels '51 having substantially spherical sides.

Having described our invention, we claim :1 1. The combination of transversely -disposed yokes, channeled pintles journaled in the furcations of said yokes, the inner ends of said pintles being beveled and provided with notches," and a stud having an edge en;-

gaged "in" said notches and a channel com- 3 municating with the channels of said pintles.

2. The combination" .oftransversely disposed yokes, a block disposed within said yokes, channeled pintles extending through the bifurcations of said yokes into said" block, the inner ends of said pintlesbeing l beveled and provided with notches, and a stud-in saidblock having an edge engaged I.

in sa'idnotches 'anda; channel communicatsin .withthejchannels of said pintles.
